* Those poems (Group X: Inofficial) were written for specific purposes and events, and I do not consider them worthy to be included into the official canon, so to say. They are however part of the enumeration.
Please note that the enumeration results from the date when the writing of the respective poem started. The date given here is the finishing date. As some took longer to finish, this may result in a significant difference between their position in the chronology, determined by the enumeration, and the actual date of finishing.
